Lockout connector arrangement for implantable medical device

Abstract

A lockout connector arrangement for implantable medical devices having at least one port for receiving a non-cardiac lead connector selectively permits only certain electrical leads to be connected to the implantable medical device. A lead connector pin of a non-cardiac lead connector is specially designed to be larger than a DF-1 lead connector pin, but smaller than an IS-1 lead connector pin. A corresponding header of implantable pulse generator has a connector port for a non-cardiac lead with a proximal-most portion that is larger than the DF-1 lead connector pin, but smaller than the IS-1 lead connector pin; and otherwise generally consistent with the other dimensions of an ISO standard IS-1 pacemaker lead connector.

CROSS-REFERENCES TO RELATED APPLICATIONS [0001] The present application is a non-provisional of U.S. Patent Application Ser. No. 60 / 584,647 (Attorney Docket No. 021433-001400US), filed Jun. 30, 2005, the full disclosure of which is incorporated herein by reference.BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] This invention relates to implantable electrical medical devices used to stimulate the heart, other tissue, and nerves, to control the functioning of the particular organ or bodily function. More particularly, the present invention is directed to electrical lead connector arrangements for implantable medical devices that selectively permit only certain electrical leads to be connected to the implantable medical device. [0004] 2. Background of the Invention [0005] Implantable pulse generator medical devices are well known in the art, and include medical devices such as pacemakers, defibrillators, baroreflex activation devices and muscle and nerve stimulator...

AI Technical Summary

Benefits of technology

[0013] The present invention is a lockout connector arrangement for implantable medical devices having at least one port for receiving a non-cardiac lead connector that selectively permits only certain electrical leads to be connected to the implantable medical device. Specifically, a lead connector pin of a non-cardiac lead connector is specially designed to be larger than the lead connector pin of a DF-1 defibrillation lead connector port, but smaller than the lead connector pin of an IS-1 pacemaker lead connector port. A corresponding header is provided for an implantable pulse generator in which a connector port for a non-cardiac lead has a proximal-most portion that is larger than the lead connector pin of a DF-1 defibrillation lead, but smaller than the lead connector pin of an IS-1 pacemaker lead. While providing for effective lockout operation, the overall dimensions of the remainder of the lead connector of a preferred embodiment of the present invention remain generally consistent with the IS-1 standards to permit the non-cardiac connector port and connectors to be manufactured with minimal changes to existing header and lead designs.
